May 6, 1930. R. H. GUENTHER HEATING DEVICE Filed Nov. 22, 1927 INVENTOR-ATTORNEY Patented May 6, 1930 RUDOLPH H. GUEN'IHER, OF CHICAGO, ILLINOISHEATING DEVICE Application filed November 22, 1927. Serial No. 235,107.

This invention relates to certain novel improvements in heating devicesand has for its principal object the provision of an improvedconstruction of this character which will be highly etlicient in use andeconomical in manufacture.

Among the several objects of the invention is to provide a simplearrangement by which the cool air adjacent the floor of a room may bedrawn into a conduit and heated and then discharge adjacent the ceilingof the room thus bringing about circulation of air within the room forheating purposes.

A further object of the invention is to pro vide a heating device for aroom which will lid include a humidifier in order that the heated airwill carry a certain amount of moisture when passing into the room.

A further object of the invention is to provide a heating device whichincludes a serpentined heated member with which air, drawn from a roomadjacent the floor thereof, will contact before being ejected in heatedcondition into the room adjacent the ceiling thereof.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings, showing the preferred form of construction and in which:

Fig. 1 is afragmentary view of a wall of a room showing my inventionassociated therewith 5 Referring more particularly to the draw ings, aWall is indicated at 10. This Wall includes a plastered surface 11 overa lath structure 12. These laths are ordinarily nailed to vertical studs13 having their lower end portions secured to a sill plate 14 and and18'respecti-vely. The entrance mouth i .is normally covered by a platplurality of perforations 20 formed. therein. A frame 21 is providedaround the. opening 22 in the wall 12 through which this entranceportion of the conduit 16 projects and mounted overt-his frame is achannel shaped frame 23 having its'inner flange 24 overlapping the edge25 of theentrance mouth. The platell) has its edge portions disposeduponthis channel frame and these edge portions and the channel frame aresecured'to the frame 21 by screw elements 26. The exit mouth of theconduit 16 pro ects through an. opening 27 formed in the wall 10 adacent the ceiling and surrounding th1s opening 18. a frame 28. 'l 'tl'f'23l l iuoancec or ex. 11s .iame k is a cianne -shaped frame 29 similarto the channel shaped frame 23 and the flange 30 of this frame over lapsthe edge 31 of the exit mouth ,of the conduit 16. A plate 32 is disposedover the exit month and this plate likewise has a plurality ofperforations formed therein. This plate has its edge portions 34.disposed uponthe channel shaped frame and are secured to.- gether withthe channel shaped frame to the frame 28 by means of screw elements 35.

The purpose of thestructure thus far'dcscribed is to admit air into theentrance mouth for passage upward through the, conduit '16 and outwardlythrough the exitmoutli 18.into the room in heated condition. The channelshaped frames 21 and 28 having. their flanges 24. and 80 overlapping theedges of the-en,- trance mouth and exit mouth ofthe conduit, willprevent escape of the heatedair to. the rear of the plaster surface, ofthewall: The air-i's-heated by a heating. denies which includesaconductor, conduity38j having a portion confined in the conduit 16formed sub.-

stantially serpentined in shape whereby; the

air passing upwardly through the conduit 16 will come into contact withthe protruding portions of the conduit 38 of the serpentined formation.The upper end portion of the conduit 38 leads to a chimney or the liketo discharge obnoxious fumes generated by the heating element. Thisheating element is indicated at 39 and is of that type ordinarily usedin connection with gas heaters and which are connected to a supply line40, passage through which being controlled by a shutoff valve 41. Thisheating unit also includes a pilot light 42 of any approved structurehaving its valve 43 disposed on the exterior side of the wall 10 forconvenient operation. The end portion 44 of the conduit 38 providesoppositely disposed notches $5 in which the unit 39 is disposed tosupport the conduit 38 with the cooperation of the studs 15 in theposition shown in Fig. 2. At the lower end portion of the conduit 38there is provided a humidifying device 46, formed serpentined information, for fiat position against the conduit This humidifying deviceincludes the pan i7 into which water is delivered through the medium ofa supply pipe 48. Passage through this pipe 48 is controlled by a valvehead 49 fixed to an arm 50 of a bell crank 51 pivotally supported at 52within the pan. The other arm 53 of this bell crank carries a float 54whereby when the water in the pan is low the bell crank will .pivotdownwardly to dispose the valve 49 from closing position with respect tothe pipe 48, thereby to allow the admission of water into the pan.

From the description herein taken in connection with the drawings, itwill be manifest that a heating device of a simple structure is providedfor heating rooms of residences, oflice buildings, and the like.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification, without departin g from the spirit of theinvention. 1, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaim.

Having thus described my invention what I claim as new and desire toprotect by Let ters Patent is:

A heating device of the character stated including a substantiallyrectangular coneuit adapted to be confined between adjacent studs andopposite faces of a wall, said conduit having an inlet opening at thelower end thereof and an outlet opening at the upper end thereof, saidopenings extending through one of the faces of said walls, a secondconduit confined within said first named conduit and being of lessthickness but of substantially the same width as said first namedconduit and having serpentine convolutions formed therein, said secondconduit extending throughout the extent thereof through the said firstnamed conduit and terminating in a flue portion extended out through theupper end of said first named conduit, said second named conduit havingan outwardly flared portion at the lower end thereof and having notchesformed in the side walls of said outwardly flared portion, a heatingelement confined within said enlarged portion and extending out throughsaid notches whereby the heat and fumes from said heating element willpass through said second conduit to heat the air surrounding the same insaid first named conduit.

In testimony whereof I affix my signature.
